The problem is that these "meta" tags cover "all" questions on the site, while there isn't a single question that needs such a tag. Can anyone give sufficient counter-examples? From a software engineering perspective, these tags are like god classes while they better fit to be used in the form of the mediator pattern (thus in the form of tag sets).

IMPORTANT COMMENT REMINDER: you may now have some questions tagged untagged, which only had these tags, which need to be retagged and/or deleted if they are of no value and unanswered for long enough .. superuser.com/tags/untagged
